Is a "bag of cash" a legal expediting fee?

Your proposition would be illegal and the responsible people and organisations prececuted for bribing a forign official in many countries including Australia and the European Union. The bribe does not have to be called a 'bribe' to contravene the law and all that is needed to trigger legal jurisdiction in Australia is for a company in the 'chain' to be present in Australia. The actul payment may be made by someone acting as an agent for a subcontractor, but the company in Australia is still liable. There have been quite a few successful prosecutions since the laws were introduced.  

I would expect the laws are similar in most advanced economies. 

Thank you for the comment, there would be no reason to do it that way if intending to be above board.  It would be an un-necessary risk because both parties would be in legal jeapordy if either party did not report correctly.  I assume paying in cash would not be in-nately illegal if handled legally.
